A prophylactic and therapeutic agent for inflammatory intestinal diseases comprising as the active ingredient a chromanol glucoside represented by general formula (1), wherein R1, R2, R3, and R4, which may be the same or different, represent each a hydrogen atom or a lower alkyl group; R5 represents a hydrogen atom, a lower alkyl group, or a lower acyl group; X represents a monosaccharide residue or an oligosaccharide residue wherein the hydrogen atom(s) of the hydroxyl group(s) in the saccharide residue may be substituted with a lower alkyl group or a lower acyl group; n is an integer of 0 to 6; and m is an integer of 1 to 6. Since it contains as the active ingredient the chromanol glucoside which is soluble in water and possesses excellent antioxidation activity and anti-free radical activity, it can significantly prevent any pathological change in inflammatory intestinal diseases and markedly improve the pathology. Further, it can be made into an aqueous preparation containing the active ingredient in a high concentration and the aqueous preparation can effectively act in a small amount on the affected part to prevent or treat inflammatory intestinal diseases and, since no side effect accompanies, can be very safely used.
一种肠道炎症性疾病的预防和治疗剂,其活性成分包括通式(1)代表的
色醇葡萄糖苷,其中R1、R2、R3和R4可以相同或不同,各自代表氢原子或低级烷基;R5 代表氢原子、低级烷基或低级酰基; X 代表
单糖残基或
寡糖残基,其中糖残基中羟基的氢原子可被低级烷基或低级酰基取代; n 是 0 到 6 的整数;m 是 1 到 6 的整数。由于它的有效成分是可溶于
水的色原醇
葡萄糖苷,具有极佳的抗氧化活性和抗自由基活性,因此可以显著预防肠道炎症性疾病的病理变化,明显改善病理状况。此外,它还可以制成含有高浓度活性成分的
水制剂,该
水制剂只需少量就能有效地作用于患病部位,预防或治疗肠道炎症性疾病,而且由于没有副作用,使用非常安全。
